<h1>From JavaScript to R</h1>
<p>Imagine if you will that instead of displaying a somewhat anodyne alert it was one that actually mattered where the user is warned that clicking “OK” will execute an irreversible action like the deletion of a record. In order to implement this the server would need to “know” whether the user has clicked said “OK” button. To do so one needs to pass data from the client to the server.</p>
<p>This can be done by defining a new <em>simplified</em> shiny input. While one can define a fully-fledged shiny input that can be registered, updated, etc. there is also a simplified version of the latter which allows sending reactive input value to the server where it can be used just like any other inputs (<code>input$id</code>). The value of the input can be defined using the <code>setInputValue</code> method which takes the id of the input and the value to give it.</p>
<div class="sourceCode" id="cb128"><pre class="sourceCode r"><code class="sourceCode r"><span id="cb128-1"><a href="from-javascript-to-r.html#cb128-1"></a>tags<span class="op">$</span><span class="kw">script</span>(</span>
<span id="cb128-2"><a href="from-javascript-to-r.html#cb128-2"></a>  <span class="st">&quot;Shiny.addCustomMessageHandler(type = &#39;send-alert&#39;, function(message) {</span></span>
<span id="cb128-3"><a href="from-javascript-to-r.html#cb128-3"></a><span class="st">    </span></span>
<span id="cb128-4"><a href="from-javascript-to-r.html#cb128-4"></a><span class="st">    // show alert</span></span>
<span id="cb128-5"><a href="from-javascript-to-r.html#cb128-5"></a><span class="st">    alert(message);</span></span>
<span id="cb128-6"><a href="from-javascript-to-r.html#cb128-6"></a></span>
<span id="cb128-7"><a href="from-javascript-to-r.html#cb128-7"></a><span class="st">    // set to true when clicked OK</span></span>
<span id="cb128-8"><a href="from-javascript-to-r.html#cb128-8"></a><span class="st">    Shiny.setInputValue(&#39;delete_alert&#39;, true);</span></span>
<span id="cb128-9"><a href="from-javascript-to-r.html#cb128-9"></a><span class="st">  });&quot;</span></span>
<span id="cb128-10"><a href="from-javascript-to-r.html#cb128-10"></a>)</span></code></pre></div>
<p>As mentioned earlier <code>alert</code> blocks code execution, therefore the input value will not be defined before the button “OK” is pressed. The server can now access the <code>input$delete_alert</code> input which is by default <code>NULL</code> and set to <code>TRUE</code> when the user has pressed “OK,” as done in the application below which prints the input to the console when the button is clicked.</p>
